<p>PROBLEM TO BE SOLVED: To provide a laminate including a fluororubber and an acrylic rubber which can be firmly bonded.SOLUTION: The laminate includes a non-fluororubber layer (A) and a fluororubber layer (B) laminated on the non-fluororubber layer (A). The non-fluororubber layer (A) is formed of a rubber composition for vulcanization. The rubber composition for vulcanization includes an unvulcanization acrylic rubber (a1), at least one compound (a2) selected from the group consisting of a salt of 1,8-diazabicyclo(5.4.0)undecene-7, a salt of 1,5-diazabicyclo(4.3.0)-nonene-5, 1,8-diazabicyclo(5.4.0)undecene-7, 1,5-diazabicyclo(4.3.0)-nonene-5, and imidazole, and at least one compound (a4) selected from the group consisting of iron dithiocarbamate and an aldehyde amine vulcanization based vulcanizing agent. The fluororubber layer (B) includes a fluororubber composition which contains a fluororubber (b1).</p> |
